SENSITIZATION OF BAKERS AND CONTROLS AS E VALUATED BY SKIN-TEST (PRICK) OR IGE-EVALUATION (EAST)

Out of 88 persons from bakeries, in which health problems have been in dicated, many show sensitization against allergen extracts from wheat flour, rye flour, soy beans and alpha-amylase of Aspergillus oryzae, b ut not against the storage mite Acarus siro and cellulase of Aspergill us niger. For the 'bakers' and 43 control persons we got similiar resu lts in the skin test (Prick) and the IgE-evaluation by EAST. The cross -classification of the EAST with the different allergen extracts is gi ven and analyzed. Almost all bakers with a positive EAST with one of t he allergens are also sensitized against wheat flour. That is not comp letely explained by the higher prevalence of sensitization against whe at flour.
